Frontal Electroencephalogram Asymmetry and Temperament Across Infancy and Early Childhood: an Exploration of Stability and Bidirectional Relations
Child development(2015)
摘要
The stability of frontal electroencephalogram (EEG) asymmetry, temperamental activity level and fear, as well as bidirectional relations between asymmetry and temperament across the first 4years of life, were examined in a sample of 183 children. Children participated in annual laboratory visits through 48months, providing EEG and maternal report of temperament. EEG asymmetry showed moderate stability between 10 and 24months. Analyses revealed that more left asymmetry predicted later activity level across the first 3years. Conversely, asymmetry did not predict fear. Rather, fear at 36months predicted more right asymmetry at 48months. Results highlight the need for additional longitudinal research of infants and children to increase understanding of bidirectional relations between EEG and temperament in typically developing populations.
